DEVICE FOR DISPENSING AND APPLYING AN ADHESIVE TAPE Filed Sept. 15, 1.95! 2 Sheets-Sheet 2 A 7' TOR/V575 United States Patent DEVICE FOR DISPENSING AND ADHESIVE TAPE APPLYING AN The present invention relates to a device for dispensing and applying an adhesive tape.

An object of the present invention is to provide a device for dispensing and applyingan adhesive tape to a surface.

Another object of the present invention is to provide a device for dispensing and applying an adhesive tape which lends itself to one hand operation, one having a simple structure, one sturdy in-construction and economical to manufacture andassemble, and one which is highly effective in action.

These and other objects and advantages of the present invention will be fully apparent from the following description when taken in connection withthe annexed drawings, in which:

Figure 4 is a fragmentary elevational view of the front portion of the device;

Figure 5 is a sectional view taken onthe line 5-5 of Figure 3;

Figure 6 is a sectional view taken on the line 6-6 of Figure 3;

Figure 7 is a fragmentary elevational view, on'a reduced scale, showing how the device of the present invention is pushed along a surface to be taped;

Figure 8 is an isometric view of a portion of the device;

Figure 9 is an'isometric view of another portion of the device of the present invention;

Figure 10 is an isometric view of still another portion of the invention;

Figure 11 is an isometric view of a blade member used inthe device; and g V Figure 12 is an elevational view similar to Figure 7, showing how the tape is started on the surface of the article to be taped.

Referring in greaterdetail to the drawings in which like numerals indicate like parts throughout the several views, the device of the present invention comprises a handle of U-shaped cross-sectional configuration arranged in an upwardly sloping direction and having a web 12 and a pairof spaced 'parallel flanges 14 and 16 projecting perpendicularly from the web 12. The exten'or surface of the web 12 constitutes a front face and the interior surface of the web 12 ,constitutes a rear face.

The web, 12 is cut away adjacent one end of the handle 10 to form a slot in which is mounted a. wound roll of tape having a free end, the roll. being designated by the reference numeral 18in the free end, shown in Figures 1, 3 and 7, being designated by the reference numeral 20: The roll 18 is mounted upon a pin 22 for free rotation while unwinding aboutthe'pin 22 as an axis transverse of the handle 10:and adjacent to;and inwardly of the upper end of the handle 10. The pin 22 traverses the slot provided in the upper end portion of thehandle 10.

The tape on the roll 18 is. of. the type having onetface 2,846,106 Patented Aug. 5, 1958 2 carryingan-adhesive coating with a separable ribbon covering the face havingthe coating. A portion ofthe, ribbon after separation from the tape is shown in- Figures1and3 and designated by the reference numeral 24 The front face of the handle 10 below and spaced from the roll 18 is provided with a slot 26. Most conveniently, the slotv26 is provided in the web-28 of a channel-shaped piece.30 which has its flanges 32 and 34 overlying-and embracingly engaging the flanges 14 and 16 of the handle The space between the flanges 14 and 16 adjacent the inner surface of the web 12 constitutes a tunnel extending along the rear face ofthehandle 10 inwardly from the lower end of the handle 10 -and terminating at a pointadjacent-to and below the roll 18.

The piece 30 is provided with a fixed pointed tongue 36 positioned withinthe tunnel so formed so that the point thereof faces toward the roll 18 andis inwardly ofthe-upper wall of-the slot 26 provided in the piece30: The base portion of the tongue 36 is formed contiguously with the web 28of the piece 30 and is in registry with the slot26 provided in-the piece 30.

A guideelement 38 provided on its upper end witha knife blade projects inan upwardly direction from the front face of-the piece 30 adjacent the lower end of the handle 10 and has theknife blade, of V-shape, spaced below and in alignment withthe slot 26.

A-block 40'is inserted into the lower end portion of the handle 10with the front face thereof under the web 12 of the handle 10 and with its side faces embracingly engaged bythe flanges 14 and 16 of the handle 10.- The block 40 is secured to the lower end portion of the handle 10 by means of nutand bolt assemblies 42 which extend through appropriately spaced bores 44 in the block 40 and-aligned holes 46 in the flanges 14 and 16. The lower end portion of the block 40 is provided with a convexly curved face portion, asat 48 in Figure 9, which provides a tape directing and applying surface as shown in Figures 1, 3,7 and'12.

The piece 30 is provided on-its upper end with a lip 50 which is received within an appropriately arranged slot 52 in the web 12 of the handle 10 upwardly of an opening 54 provided inthe web 12.

The block 40 is provided with a bore 54 extending in; wardly from-the rear face thereof and terminating at the rear face-of a chamber 56provided in the block 40 which has its forward end opening out of the tape directing and applying surface 48 of the block 40. A blade mem{ ber 58 having acutting head 60 on one end and a handle 62"on the other end is positioned with the portion adjacent the end having the handle 62 exteriorly of the rear face of the handle 10 and with the cutting head 60-within the chamber 56, The blade member 58 is reciprocatingly mounted in the block 40 for movement from the position in which the cutting edge of the head 60 is inwardly of the surface 4810a position inwhich the cutting edge projects .out of. the surface 48'to thereby sever the sepa rated tapeas the latter moves over the surface 48;.

A portion ofthe-tapereceived from the roll 18 adjacent the free end-thereof is movable in responseto;

unwindingmovement of theroll 18; the tape moving from the roll-18 intothe tunnel provided between the flanges 14 and 16 of the handle 10 and uponbeing moved through thetunnel thus 1 formed having in turn the end edge penetrated between theseparable ribbon 24 and one face of-tthe tape carryingtneadhesive coating by thehpoint of the tongue 36-10 separate the ribbon 24 fromthe tape,

the separated-ribbon 24. being m ved Out ofthe slot 261 in thepiece .30: and; over the knifeblade of the. guide ele; meat 38,-- Thetapa separa ed from he ribb n24,pmeves along .and out of, the tunnel and overthe directing and applying. surface-48 and; backwardly along. inabutflag:

, 3 engagement with a surface 64 to which the tape is to be applied. In Figure 3, the free end portion 20 of the tape has been secured to the surface 64 and in Figure 7 the blade member 58 has been manually advanced to a position in which the cutting edge of the head 60 projects outwardly of the chamber 56, severing the tape and leaving the end portion 20 of the tape securely fixed to the surface 64.

The portion of the tape still projecting over the forward portion of the surface 48 may be next applied to another surface to be taped, as shown in Figure 12, by rocking movement of the handle 10 in a counterclockwise direction to a position in which the surface 48 is downwardly with an end portion 20' of the tape between the surface 48 and the surface 64. The device of the present invention is now in position for moving once more to the upwardly sloping direction position shown in Figures l, 3 and 7, in which the device may be pushed along the surface 64 drawing from the tunnel formed therein the adhesive tape and applying the same to the surface to be taped. At intervals, the ribbon 24 may be severed by drawing the same over the cutting edge or knife blade of the guide element 38.

Although the device has been described for use with an adhesive tape having a separable ribbon covering the adhesive coating on the tape, it is to be understood that it may be used for tape without such separable ribbon.

While only a single embodiment of the present inventionhas been shown and described, other embodiments are contemplated and numerous modifications and changes may be made therein without departing from the spirit of the invention as set forth in the appended claims.
